There is one Arabic string as: اختبار عرض اللغة العربية في QTE. The displaying on QLabel and QPushButton is different with same interface setText(). See picture below:

enter image description here

Anyone can help on why the displaying behavior is different?

possibly you need to change the direction of the layout. in detail here

setLayoutDirection(tr("LTR")=="RTL" ? Qt::RightToLeft : Qt::LeftToRight)

  • Thanks for the suggestion. It seems that it takes effect when use qApp->setLayoutDirection(Qt::RightToLeft). But this will also affect the overall application layout. Here I only want to change the string direction on QPushButton to make it same as QLabel. However qPushButton->setLayoutDirection(Qt::RightToLeft) doesn't have effect. – jaredzhou Nov 26 '21 at 03:47
